Title: Heat ray reflecting laminated sheet
Inventor: KAWAGUCHI ATSUSHI
IPC: C03C17/36
Filed: 1989-07-07
Abstract: PURPOSE:To obtain the title nice-looking heat ray reflecting laminated sheet looking almost uncolored by providing a layer sandwiched between a noble metal layer and a metal oxide layer between a transparent sheet and a transparent resin film in the title sheet obtained by laminating two transparent sheets with the transparent resin film. CONSTITUTION:The first metal oxide layer 11 consisting of ITO (contg. 10% tin oxide and 90% In oxide) is formed on a glass sheet 10 by sputtering, for example. The noble metal layer 12 consisting of silver and having 4-10 ohms/ square sheet resistance is formed thereon in the same way. The second metal oxide layer 13 consisting of ITO is formed thereon. The sum of the thicknesses of the layers 11 and 13 is controlled to 500-900Angstrom , and the ratio of the layer thickness of the layer 13 to that of the layer 11 to 1.1-1.6. A PVB film 14 and a glass sheet 15 are then sucessively laminated on the layer 13, and fused to each other. By this method, a laminated sheet wherein the color tone of the reflected light belongs to the color tone indications (a) and (b) of the Hunter's color table, fulfilling -1<=a<=1 and -1<=b<=1, and having <=10% visible ray reflectivity is obtained.

IPC: G05D3/12
Filed: 1983-09-27
Abstract: PURPOSE:To attenuate quickly only transient vibration without exerting bad influence upon positioning accuracy by providing a vibrator obtained by putting a visco-elastic material between long elastic plates and fitting a weight to one end part of the long elastic plate to a carriage body or a rotary shaft of a step motor. CONSTITUTION:The vibrator 7 is constituted by putting the visco-elastic material 10 between the long elastic plates 9a, 9b and one side of the weight 11 is made free side and fixed on the periphery of the carriage body or the rotary shaft of the step motor. For instance, an SUS plate can be used as the elastic materials 9a, 9b and buthyl rubber or the like can be used as the visco-elastic material 10. Such kind of a vibrator 7 vibrates severely in accordance with the transient vibration of the carriage body, large shear distortion is generated on the visco-elastic material 10 and the energy of transient vibration is smoothly dispersed from the vibrator 7 due to the dumping effect of viscosity. Since the vibration direction of the vibrator 7 is made to coincide with the moving direction of the carriage body, dumping is executed more effectively.

Title: Control system for buffer memory
Inventor: HANEZAWA YASUSHI
IPC: G06F12/10
Filed: 1985-08-12
Abstract: PURPOSE:To avoid the deterioration in efficiency due to a replacement by carrying out an access for the retrieval of an address conversion table word when the PTW is registered to a TLB as well as the registration of said table word only with a cache memory for instructions. CONSTITUTION:An instruction buffer memory part 1 contains an instruction cache 2 and an instruction TLB 3. An operand buffer memory part 4 contains an operand TLB 6. A control part 7 retrieves both TLB 3 and 6 to obtain a real address. However the part 7 gives an access to a real memory to obtain an address conversion table and then starts a paging part 8 to obtain a real page address in case the retrieval of the TLB fails. The part 8 uses the cache 2 to perform the real memory access for the retrieval of the address conversion table word and registers the address conversion word to a cache memory with the cache 2 only. Thus it is possible to avoid the deterioration of the using efficiency of the buffer memory due to the replacement caused by the irregularity of addresses.
